This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X600-10, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X600-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10
The AirTAC SIJ63X600-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the direct replacement SAIJ63X600-10. It features a 63mm bore, G3/8 port, and a 600mm nominal stroke that an external stop screw can trim by up to 10mm on-site, yielding a usable extend stroke of 590-600mm. This stop sets the end position but is not a load lock.
The SAIJ replacement retains the exact interface, mounting, and porting, while adding an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. This SKU lacks a -S magnet and cannot accept a sensor. At 600mm stroke, external guides are advised to prevent rod bending under side loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10 Is Used
Press Fit Tuning
Adjusting the final 10mm extend position on-site to set precise insertion depth for bearing press operations without machining spacers.
Divertor Stop
Trimming the extend stroke by a few millimeters to fine-tune the stopper block position for varying package sizes on a sorting line.
Clamp Positioning
Setting an exact clamping reach on a machining fixture, allowing 590-600mm of travel to compensate for part tolerances.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10 with the SAIJ63X600-10
To replace the discontinued SIJ63X600-10, order the direct replacement SAIJ63X600-10, which preserves the 63mm bore, 600mm stroke, 10mm adjust window, G3/8 port, and ISO 15552 mounting. The 10mm adjust window is ideal for fine-tuning the extend end position without shims. Mounting options include FA, LB, and TC brackets. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For the 600mm stroke, use external guides to manage side-load and rod-bending risks. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X600-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X600-10 FAQ
Yes, the SIJ63X600-10 is discontinued. The direct replacement is the SAIJ63X600-10. It shares the same ISO 15552 interface, 63mm bore, 600mm stroke, 10mm adjust window, G3/8 port, and mounting options, while upgrading the piston seal.
The external stop screw provides a 10mm adjust window, shortening the 600mm extend stroke to 590mm. This stop sets end position and is not a load lock.
